Windmill pump attachment



Patented Nov. 1, 1938 UNITED STATES PATENT oFFlcE WINDMILL PUMP ATTACHMENT Rufus Hamond Price, Carrizo Springs,rTex. Application March 24, 1938, Serial No. 197,921 1 Claim.` (Cl. 267-70) The present invention relates to new and useful improvements in windmill pumps and has for its primary object to provide, in a manner as hereinafter set forth, an attachment -comprising novel means for equalizing the load on the driving mechanism on the up and down strokes of the sucker rod, thus permitting the windmill to be driven by a comparatively light wind in addition to substantially eliminating or materially reducing shock and jar.

Other objects of the invention are to provideA an equalizer Vof the aforementioned character for windmill pumps which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured and installed at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference Y designate corresponding parts throughout the Vseveral views, and wherein:

Figure 1 is a View in vertical section through an embodiment of the invention, showing the device installed.

Figure 2 is a view in horizontal section, taken substantially on the line 2-2 of Fig. 1.

Figure 3 is a view in horizontal section, taken substantially on the line 3 3 of Fig. 1.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a collar I of suitable material, preferably metal, which is releasably secured in adjusted position on the sucker rod 2 of the windmill through the medium of a set screw 3. Fixed on the collar I and depending therefrom in spaced, concentric relation to the sucker rod 2 is a tubular housing 4. 'I'hreadedly mounted in the upper end portion of the pump casing 5 is a tubular metallic housing 6 which extends slidably into'the housing 4. This is shown to advantage in Fig. 1 of the drawing. Fixed in the lower end portion ofthe tubular housing 6 is a disc 'l having an opening thereposition thereon, a tubular scopic housings 4 and 6 and has one end engaged with the disc 1 and its other end engaged beneath the collar l for yieldingly supporting the sucker rod. Y

It is thought that the operation of theV device 5 will be readily apparent fromk a consideration of the foregoing. On the down stroke of the sucker rod 2 the coil spring 8 is compressed. Then, on the up stroke of the sucker rod the coil spring 8 materially assists in lifting the load. 10 Of course, as the sucker rod 2 moves upwardly and downwardly the housing 4 reciprocates on the lower housing 6.

It is believed that the many advantages of an equalizer for windmill pumps constructed in ac- 15 cordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and ar- 20 rangement of parts may be resortedto which medium of a two part clamp.

What is claimed isz In a windmill pump comprising a casing and a sucker rod operable in said casing, a collar 30 adjustably mounted on the sucker rod above the casing, a, set screw in said collar enga-geable with the sucker rod for securing the collar in adjusted housing xed on thecollar and depending therefrom in spaced con- 35 centric relation to the sucker rod, a tubular housing threadedly mounted in the casing and eX- tending slidably into the first named housing, a disc xed in the lower portion of the second named housing, said disc having an opening 40 therein accommodating the sucker rod, and a coil spring mounted in the housings and encircling the sucker rod and having its lower end .engaged with said disc and its upper end engaged beneath the collar for yieldingly urging 45 Athe sucker rod upwardly.
